# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Final rule.

# SUPPLEMENTARY INFORMATION:

## Authority for This Rulemaking

The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it modifies Class D airspace and Class E airspace designated as a surface area and revokes Class E airspace designated as an extension to the Class D or Class E surface area to support IFR and VFR operations at Buckley Space Force Base, Aurora, CO.

## History

                    The FAA published an NPRM for Docket No. FAA-2024-1857 in the                     **Federal Register**                     (89 FR 73022; September 09, 2024), proposing to amend the Class D airspace and Class E airspace designated as a surface area and revoke the Class E airspace designated as an extension to the Class D or Class E surface area Buckley Space Force Base, Aurora, CO. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. Two comments were received in favor of the proposal.                

## Incorporation by Reference

                    Class D, E2, and E4 airspace designations are published in paragraphs 5000, 6002, and 6004, respectively, of FAA Order JO 7400.11, Airspace Designations and Reporting Points, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This document amends the current version of that order, FAA Order JO 7400.11J, dated July 31, 2024, and effective September 15, 2024. FAA Order JO 7400.11J is publicly available as listed in the                     **ADDRESSES**                     section of this document. These amendments will be published in the next update to FAA Order JO 7400.11.                

FAA Order JO 7400.11J lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.

## The Rule

                    This action amends 14 CFR part 71 by modifying the Class D airspace and Class E airspace designated as a surface area and revoking the Class E airspace                           ( print page 104406)                        designated as an extension to the Class D or Class E surface area at Buckley Space Force Base, CO.                

The lateral boundaries of the airport's Class D and Class E surface areas are insufficiently sized and expanded to the southeast to better contain IFR arrivals when less than 1,000 feet above the surface and departing IFR aircraft until reaching the next adjacent airspace. Additionally, an approximately 0.30 nautical mile gap between Class E and Class G airspaces is closed by merging the Buckley Space Force Base and Centennial Airport surface areas. As such, the Buckley Space Force Base Class D and Class E surface areas are modified to be within a 4.4-mile radius of the airport, within 2 miles northeast and 4 miles southwest of the airport's 151° bearing extending to 7.1 miles southeast, and within 4 miles south and 4.4 miles north of the airport's 270° bearing extending to 4.7 miles west, excluding that airspace within the Denver International Airport Class B and Centennial Airport Class D airspace areas.

Buckley Space Force Base's Class E airspace designated as an extension to the Class D or Class E surface area is revoked. The Class E extension is no longer required due to the expansion of the airport's surface area airspace.

Finally, the administrative portions of the airport's legal descriptions are modified to match the FAA's database. The airport's name on line two of both legal descriptions is changed to read “Buckley Space Force Base, CO.” Additionally, line four of both surface area legal descriptions now include “Denver International Airport, CO” and “Centennial Airport, CO” as references, as they are used to define the airport's surface areas.

## Regulatory Notices and Analyses

The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore: (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

## Environmental Review

The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, paragraph 5-6.5.a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.
